I tend not to worry about what is going to happen because there is nothing I can do about it anyway. But that being said,I will be as prepared as possible. The younger generation seems to freak out at the slightest problem , at least the ones here. I am glad I grew up poor and in a area of the US that still had outhouses ,no central heat, wood stoves and no running water. Copper mining area of the late 50s and early 60s in AZ. I can grow my own food , kill my own animals ,(if need be,, yuck though) . Sew , cook on a wood stove, and all the other things that will need to be done. I figure if me and mine are going to survive what ever , if its surviveable, I don't have time to wail and worry, won't be on my knees either except to plant or clean. I will be working.
In my way of thinking watching these sci fi movies is a form of education, maybe if we listen we can stop it happening. How many things in old sci fi movies are around today?
